摘要

针对一款单模复合动力分流混合动力系统，分析了混合动力系统的主要工作模式和不同挡位的特点.在LMS/AMESim环境中建立了混合动力系统的关键部件物理模型，并通过应用程序接口与Matlab/Simulink建立的系统控制模型集成联合仿真模型.利用该联合仿真模型进行了整车经济性仿真，并与实际转鼓台架试验结果进行了比较.结果表明：混合动力汽车与基础车型相比综合节油率达到38%，建立的物理模型精度较好，与实车测试结果较为贴近，仿真误差均在5%以内，能够服务于系统优化和策略开发，减少了实际开发过程中的复杂测试过程，大大提高了开发效率.

Abstract

For the single-mode compound power-split hybrid system, the main working modes and the characteristics of different gears were analyzed. In the LMS/AMESim environment, the plant models of key components of the hybrid system were established, and the joint simulation model was integrated with the system control model established by Matlab/Simulink through the application program interface (API). The economic simulation of the vehicle was carried out by the joint simulation model, and the simulation results were compared with the test results of actual vehicle on chassis dynamometer. The results show that compared with the basic vehicle, the comprehensive fuel-consumption saving rate of the hybrid electric vehicle is 38%. The simulation error is within 5%, which is close to the actual vehicle test result. The established plant model has good accuracy, which can serve for system optimization and strategy development. The complicated testing process in the actual development process can be reduced, and the development efficiency can also be significantly improved.
